Tried it.  Don't work.  the no_image tag makes povray completely ignore the
ambient, even when turned up to 10 billion.

I also tried having a lightsource with looks_like.  Terrible results.

I'd like to have a macro that just defines a texture to put on top of the
existing texture of any pre-existing object (low temperatures, the original
texture shows through fully, high temperatures, the ambient and heat color
take over)...but if its not possible, then its not possible.
